I call your attention to the above.
You will of course notice that the 2015 max was around 404 ppm, and the 2016 max is 408.5 ppm.
It looks like the minimum might not go under 400 ever again (as I have said more than once.)
2015 min: 395.5 ppm
2016 min: 308 ppm.
I extrapolate 2016 min in late September to be 401 ppm.
Hillary and your Team, get with it!
As Steven D said elsewhere, climate change is the greatest threat to world peace.
The Department of Defense agrees.
